Hi Hauke,

Updated the file header per your suggestion.

Subject: [PATCH] ARM: dts: BCM5301X: Add basic DT for Linksys EA6500 V2

It's wireless home router based on BCM4708A0 with BCM4360 + BCM4331
wireless chipsets. The 5GHz chip currently isn't supported only due
to missing compatible firmware.

the DTS here was based on the Linksys EA6300 V1 DTS, only changing
the model strings
